Trump: sanctions on Iran "will soon be increased, substantially"

President Donald Trump accused Iran on Wednesday of secretly enriching uranium for a long time and warned that U.S. sanctions will be increased soon, as the U.N. nuclear watchdog held an emergency meeting on Tehran's breach of a nuclear deal.

"Iran has long been secretly 'enriching,' in total violation of the terrible 150 Billion Dollar deal made by John Kerry and the Obama Administration. Remember, that deal was to expire in a short number of years. Sanctions will soon be increased, substantially!" Trump said on Twitter.
